Hi all, My device driver has fifo which is basically linked list,i had written a test program which writes 10000 times to device driver, the driver everytime executes 'kmalloc' for new item whenever device write method invokes and stores the data item in list. my question is that as it is giving segmentation fault i have checked every pointer carefully, is any memory constraint upto which kernel allocates memmory for driver, and my test program is mlock in memory but its user space program, but is there any limit beyond which kernel not allocates the memory for driver and second question is in 2.6 kernels , is it possible to interrupt the timer0 handler when its executing normal schedular code,i mean to say is is it the case that timer0 is interrupted by some other interrupt and thus delaying the execution of timer0 interrupt. thanks in advance __________________________________ Do you Yahoo!?
